Abstract
A temperature-time program, i.e., continuous cooling annealing (CCA), was studied for the crystallization of amorphous alloy. The CCA crystallization behavior of Cu33Zr67 amorphous alloy was investigated by differential scanning calorimetry. Kinetic analysis indicates that commonly used methods (e.g., the Kissinger plot) become invalid. The general kinetic theory was applied for describing the CCA crystallization kinetics, and two kinetic recipes were proposed for the determination of kinetic parameters. By applying them to the measured data, reasonable parameter values were obtained. Accordingly, the CCA crystallization mechanisms of Cu33Zr67 amorphous alloy were determined as approximately continuous nucleation and 3-dimentional interface-controlled growth.
